Which actor did Anna Maxwell Martin replace as Sarah Nelson?

Anna Maxwell Martin replaced Olivia Colman as Sarah Nelson in *Heartstopper Forever*.

Colman played Sarah, Nick Nelson’s mother, in the first two seasons of *Heartstopper*. Her performance became especially associated with Nick’s coming-out scene, when Sarah responds with warmth and reassurance rather than rejection. The moment helped establish her as a key supportive parent in the series.

Colman did not return for the finale, so the production recast the role with Martin. Martin therefore continues the character rather than portraying a different member of the Nelson family. The change is easy to miss in quiz options because all four names are established British actors, but only Colman previously played Sarah.

Sarah should also not be confused with Charlie’s mother, Jane Spring. The two characters represent different family dynamics in the story, with Sarah generally serving as an important source of emotional support for Nick and Charlie.
